Speed DDR4 2133 (PC4 17000)

  • 32 GB capacity with two 16 GB modules for multitasking headroom
  • DDR4 2133 MHz speed rated at PC4-17000 for responsive performance
  • CL15 latency at 1.2 V standard voltage for efficient operation
  • Dual-rank 2Rx8 organisation on 288-pin DIMMs for desktop compatibility
  • Rigorously tested non-ECC unbuffered kit backed by lifetime warranty

Capacity & Compatibility

This 32 GB kit contains two 16 GB DDR4 DIMMs that run at 2133 MHz with a CL15 latency. The modules operate at the standard 1.2 V and use the 288-pin unbuffered non-ECC form factor. They are built as a dual-channel kit and are tested for compatibility with a wide range of desktop systems from major manufacturers.

Sustained Load Behaviour

Each module uses a dual-rank 2Rx8 organisation, which helps maintain steady throughput when the memory controller keeps multiple banks open during long workloads. The JEDEC-standard 1.2 V voltage keeps power draw predictable, so temperatures remain stable without requiring extra cooling. Testing at the rated 2133 MHz frequency ensures consistent performance over extended sessions.

Installation Notes

The DIMMs follow the standard 288-pin DDR4 layout, so they seat in any desktop DDR4 slot with the usual alignment notch. Because the kit is unbuffered and non-ECC, it works in consumer motherboards that do not support registered or error-correcting memory. Verifying the motherboard’s qualified-vendor list before purchase avoids the most common compatibility issue.

Questions about this item

How much heat and power will this 1.2 V DDR4 kit draw when running all day?

The modules operate at the standard DDR4 voltage of 1.2 V, so power draw and heat output stay low during continuous use.

What must my motherboard provide for these 288-pin DIMMs to work?

Your board needs DDR4 DIMM slots that accept 288-pin unbuffered non-ECC memory and support dual-channel operation.

Can I mix these dual-rank 16 GB modules with older single-rank DDR4 sticks?

Mixing ranks is possible but not guaranteed; the system will run at the slowest module's speed and may require manual timing adjustment.
